searching for key in multidimensional array by sub array value

Question

I am trying to unset an array by value. I only have the ExerciseID and need to unset the array that it belongs too.

My array is structured like so:

Array
(
[0] => Array
 (
 [ExerciseID] => 644
 [Sets] => 
 [Reps] => 
 )
[1] => Array
 (
 [ExerciseID] => 33
 [Sets] => 
 [Reps] => 
 )
)

Many thanks in advance.

Answer 1

Loop through the array and check for the ExerciseID key in your array with the value of your ExerciseID and if found , unset and break up from the loop.

$exid=33;
foreach($arr as $k=>$arr1)
{
 if($arr[$k]['ExerciseID']==$exid)
 {
 unset($arr[$k]);
 break;
 }
}
print_r($arr);

OUTPUT :

Array
(
 [0] => Array
 (
 [ExerciseID] => 644
 [Sets] => 
 [Reps] => 
 )
)
